Assessing Family Members’ Motivational Readiness and Decision Making for Consenting to Cadaveric Organ Donation

Abstract

This study assessed the applicability of two important components of the transtheoretical model of behavior change (TTM) to family consent for cadaveric organ donation. Men and women (N = 169), who consented or refused to donate the organs of a family member, completed a telephone survey reflecting the stage of change and decisional balance constructs. Psychometric analyses resulted in a two-factor decisional balance scale: a seven-item scale representing negative perceptions of consent (cons), and a seven-item scale representing positive perceptions of consent (pros). The pros and cons were significantly associated with stage of readiness for donation consent and with the family consent decision. Research utilizing this measure has the potential to enhance intervention programs to increase donation consent rates.

Measuring kidney patients’ motivation to pursue living donor kidney transplant: Development of Stage of Change, Decisional Balance and Self-Efficacy measures

“…However, as providers initiate conversations about the possibility of LDKT, having the ability to accurately assess individual patients’ readiness to pursue LDKT, weighing of the risks and benefits of LDKT, and confidence in their own ability to find a living donor is very important. One theory of behavioral change, the transtheoretical model (TTM), has already been successfully applied to transplant decision-making, specifically organ donation decision-making (Hall et al, 2007; Robbins et al, 2001) and whether ESRD patients would pursue DDKT (Waterman et al, 2010a). The TTM explains motivation and intentional behavior change based on thoughts, experiences, and behaviors and comprises four key constructs: Stage of Change (SOC), which measures how patients’ motivation to take specific behavior changes through time (Prochaska and DiClemente, 1983); Decisional Balance (DB), an assessment of how a patient weighs the Pros and Cons of behavior change (Velicer et al, 1985); Self-Efficacy (SE), which captures whether an individual believes they can make or sustain a behavior change in difficult situations (Bandura, 1977); and Processes of Change, which capture experiential and behavioral strategies used to facilitate behavior change.…”

Disease prevention without relapse: Processes of change for HPV vaccination

“…However, one cannot relapse from vaccination, and thus the Action and Maintenance stages are combined for this application of the TTM to HPV vaccination. This staging modification has been successfully applied in organ donation research in the past [24,25], but this is the first published application of the Processes of Change to a behavior without a Maintenance stage.…”

Social marketing on AIDS: using Transtheoretical model to understand current condom usage among commercial drivers in Accra, Ghana

“…From initial studies of smoking, the TTM rapidly has expanded to include investigations and applications to a broad range of health and mental health behaviours, mammography and cancer screening, medication compliance, HIV testing intentions, unplanned pregnancy prevention, pregnancy and smoking, sun exposure and physicians practicing preventive medicine (Prochaska et al ., ). The largest number of TTM‐related intervention studies have focused on smoking cessation (Aveyard et al ., ; Hollis et al ., ; Dijkstra et al ., ; Hall et al ., ); Diet (Brug et al ., ; Horwarth, ) and exercise (Marcus et al ., ).The number of applications are growing, from alcohol abuse (Carbonari and DiClemente, ), to condom use (Parsons et al ., ; Redding et al ., ), to organ donation (Robbins et al ., ) and multiple behavioural changes (Gold et al ., ; Steptoe et al ., ). If interventions are to be effective, the stage distributions of specific high‐risk behaviours should be known (Proschaska, et al ., ).…”
